Naturalight Systems Limited have recognised the importance of non-fragility of glass roof assemblies and extensively researched the need for such within the current marketplace. As ACR(M) 2005:001 ‘non-fragility of roofing assemblies’ cannot be applied to glass rooflight structures where many thought it could be, advice was sought from CWCT and the outcome was that Naturalight Systems Limited tested and had passed a NaturalSpan rooflight assembly to TN66 / TN67.
